Re: Preventing selection event propagation

I have a confirmation window to be first displayed on tab selection,
and only on click of "No" button in the confirmation window the tab
selection should be cancelled.
Currently both BeforeSelectionEvent and SelectionEvent are invoked
since I can perform event cancel() on "No" button.
